To all whom it may-concern: J I

Be it knownthat 1, WILLIAM G. PILK- INTON, a citizen of the United States, residing' at Buifalofln the county of Erie and State of New York, have invented certain new and-usefulImprovements in Devices for Transferring and Dispensing Liquid, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to devices for transferring and dispensing liquid and is particularlyuseful in pharmaceutical work and for other commercial purposes such as filling fountain pens and the like.

It is my purpose to provide a device of this character through'the instrumentality' of which accurate quantities of a liquid can be transferred from one container to another and which will always indicate to the operator the amount that has been delivered to, the receiving container.

My invention can be carried into practice in various ways, but preferably I associate it with the cork or closure of the bottle from which a given'liquid is to be removed and dispensed and I will describe and illustrate the same in suchadaptation although it will be understood that its association with a cork or closure is not essential in carrying view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the claims. e V v In describing my invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the I several views, and in which Figure 1 is a vertical section of a bottle showing my invention associated with the cork thereof, the valve element of my invention being shown in open position in full line and closed position in dotted lines;

=Referr1ng to the drawings, 10 indicates a bottle containing liquid '11 and closed by a cork 12 or other suitable closure. Myimproved liquid transferring and dispensing device is shown as comprising a tubular vial 13 preferably glass and having one end sunk in the closure 12 so that the removal of the closure will effect removal of the device. The

end of the tubular vial 13 remote from the 010- sure 12 is tapered as at 14 and is normally closed by a valve 15 having a stem' 16 extendably less diameter than the associated openproper discharge of liquid when the valve isin open position. The stem 16 is carried laterally at 17 and then returnedinwardly at 18, the free'end of the portion 18 terminating in a lateral toe 19 for a purpose that will pres ently appear. Formed on. the body of the vial 13 in any suitable manner are graduations' or scales 20 through the medium of which the amount of liquid that has been dis-1 'ing to the exterior of the vial'and of consilderp'ensed can be at all times observed. For-the properoperation of my devic'e th'e body of the vial '13 is provided-with a vent opening 21 to relieve any vacuum that would occur 7 I in"dispensing'liquid' fr m the Vial- In the use of the form of my invention illustrated in Figs. 1 to 4 it will be observed that when the closure 12 is inserted in the allowing a portion of the liquid in the bottle, or container 10 to be transferred to said vial. The bottle is then righted or broughtto its normal position, as shown in Fig.1,- and when this is done the valve 15 i in the discharge end of the vial will seek its closed position under the influence of gravity so that when the closure 12 is removed the vial will carry a supply of the liquid which may thereafter be discharged as desired. To deliver any given quantity of the liquid from the vial it is only necessary to engage the toe 19 on the edge of the opening of the receptacle into which the liquid is to be delivered. By then pressing down lightly on the closure 12 the valve .15

will be lifted to open position so as to per- V mit flow of liquid from the vial 13 as clearly v in order to assure the opening of the, valve under these conditions I make the vial 13 sufliciently long with respect. to the bottle in which it is usedvto assure the engagement of the valve stem with the bottom of the bottle to effect the lifting of the valve to open position, all as is clearly shown in Fig. 5. 7

In Figs. 6 and 7 the construction of my invention is the same as that illustrated in Figs. 1 to 4 except that the opening of the valve is positively effected by engagement of they valve stemwith'the' bottom. of the I bottle, such a construction being preferably the bottle should be only partially filled resorted to where the liquid is susceptible to thickening or coagulatlon such as commercial' writing ink.

.It may be noted in connection with both forms of this inventionthat the-operator may, asfdesired, open the valve to its full extent so as to permit the liquid to pour in a stream from said vial, or he may by only allowing the valve to partially open,

permit the liquid to discharge from the vial inthe. form of drops, thewlateral extension 17 of the stem 16 of said valve facilitating this dropping operation; 7 It is to be further noted that in the event with liquid and a vial used which .does not reach to the bottom of; said bottle, then the filling of the vial is accomplished by inverting the bottle, as heretofore described, to the position shown in Fig. 2, Where the valve 15 will be opened, and permitting the liquid, which in this instance 'does not reach to the discharge end of the vial, to pass into the vial through the air vent 21, displacing the closure, and a valve for normally closing said mouth. 7

2. In a device of the character described, a solid closure or,-stopper for, bottles and like containers, a. vial secured to, and depending from said closure,said vial having.

a discharge mouth at its dependingend and a vent in'the side thereof adjacent its connection with said closure, a valve within.

the vial normally closing said mouth, and means on the valve extendingexteriorly of the vial for operating said valve.

3. In combination with a bottle or other container, a closure for said container, a vial depending from said closure and immovable with respectthereto, said vial having av dis chargemouth, a valvewithin the vialnormally closing said mouth when the vial is removed from its container, and means on the valve extending .exteriorly of the vial for operating said .valve, said-means engaging a part of the container-for holding the valve-in open position when the closure is in place with the vial positioned within said container.
